APPARATUS FOR PUNCHING MUSIC-SHEETS.

$FECIFIGATION forming part of Letters Patent N 0. 745,881, dated December 1, 1903.

Application filed December 13,1902- SerialNo.135,057. (No modehi To all 20720172 in 17mg concern:

Be it known that I, HERMANN MEYER, acitizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented a new and Improved Apparatus for Punching Music-Sheets, of which the following is a full, clear, and exact description.

The invention relates to machines for perforating m usic-sheets for self-playing musical instruments; and its object is to provide a new and improved apparatus for punching the sheets in a simple and exceedingly accurate manner according to the perforations in the pattern-sheet.

l he invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement. Fig. 2 is an enlarged sectional side elevation of the same on the line 2 2 of Fig. 3. Fig. 3 is a sectional plan View of the same on the line 3 8 of Fig. 1. Fig. 4 is a transverse section of the exhaustingbellows, the section being on the line 4 4 of Fig. 1. Fig. 5 is an enlarged end elevation of the improvement, showing the mounting of one of the winding-up drums. Fig. 6 is a similar view of the improvement, showing one of the removable spools. Fig. 7 is an enlar ed sectional side elevation of the punching devices and the means for setting the punches and for actuating the same, and Fig. 8 is a face view of one of the perforated sheets.

A pattern-sheet A is perforated according to the piece of music which it represents, and the said sheet unwinds from a spool B and then passes over a tracker-board G to wind upon a drum D, which rotates in unison with a similar drum E, on which winds a sheet or sheets F as the latter are punched while passing over a die or punching block G, the said sheet or sheets unwinding from a spool H similar to the spool B. Punches I operate in conjunction with the die-block G to punch holes in the sheet F as the latter passes over the dieblock G,and the said holes are punched in accordance with the holes in the patternsheetA registering at the time With the openings in the tracker board 0, so that the punched sheets F are exact reproductions of the pattern-sheet A, it being understood that either a single sheet F may be punched at a time or a plurality of superimposed sheets passing over the die-block G, as before mentioned.

Each of the punches I is mounted to slide in bearings l and 1 attached to the main frame J of the machine, and the punches are held normally in an' uppermostposition by springs 1 and the said punches are first moved downward into a setting position previous to punching the holes by levers K, fulcrumed at K on-the main frame J and engaging with their forward ends the upper ends of the punches I, as plainly indicated in Figs. 2 and '7. The inner ends of the setting-levers K are connected with a pneumatic means L for moving the levers and punches into setting position, and the said pneumatic means are controlled from the sheet A as the latter passes over the tracker-board O, and when the levers have moved into the setting position they are then acted on by transverse shoulders or projections N on a shaft N, extending transversely and journaled in suitable bearings in the main frame J. Thus the setting-levers K, moved into position by the pneumatic means L, are acted on by the projections N as the shaft N rotates, so that a swinging motion is given to the said settinglevers to press the corresponding punches I downward to punch holes in the sheet or sheets F over the die-block G.-

The pneumatic means L for setting the punches as described are constructed as follows: The inner end of each lever K is engaged by a loop L, held 'on the lower end of a rod L connected with a bracket L on the movable part of a pneumatic L in communication with a chamber 0, connected by a port 0 with the outer air and by a port 0 with an exhausting-chamber P, as plainly shown in Figs. 2 and 7. The ports 0 and O are controlled by valves 0 0 respectively, secured on a valve-stem O and connected with a diaphragm 0 arranged in the exhausting-chamber P over a chamber P, having a feed-groove P opening into the exhaustingchamber P. The chamber P is connected by a flexible tube O with a corresponding opening in the tracker-board C, so that when an aperture in the sheetAregistei-s with the corresponding tracker-board opening then air passes through this opening and tube 0'' into the chamber P to press against the under side of the diaphragm 0, so as to move the same upward to cause the valve O to move off its seat over the port 0 and connect the exhausting-chamber P with the chamber 0, while the valve 0 closes the port 0', and thus disconnects the chamber O from the outer air. Now as soon as the chambers O and P are connected with each other then the corresponding pneumatic L collapses, owing to the suction action, and consequently the rod L is drawn up by the closing pneumatic, so that the corresponding lever K is swung upward at its rear end and downward at its front end to move the punch I intopunching position, and at the same time the rear end of the lever K moves into the path of the projection N, so that the latter imparts a powerful swinging motion to the lever K to cause the punch I to punch an aperture in the sheet or sheets F over the die-block G. As soon as the sheet A closes the trackerboard opening, and thereby cuts 0E atmospheric air from the tube 0 and chamber P, then the diaphragm O is immediately forced downward, so that the valve 0' moves into a closed position, while the valve 0 moves into an open position to again connect the chamber O with the atmosphere, so that the pneumatic L becomes inflated and the rod L moves downward to allow the lever K to re turn to its former position, and with it the punch I, owing to the action of its spring 1 By reference to Fig. 1 it will be seen that the pneumatics L are arranged in tiers to readily accommodate the same.

The pattern-sheet A and the sheets F to be punched travel intermittentlyin unison, and the distance between successive transverse rows of apertures in the sheet A is such that during the time the sheets A and F are at a standstill apertures in the sheet A register with the corresponding openings in the tracker-board O for the purpose above described-thatis, for actuating the corresponding punches I to punch the sheets F while stationary over the die-block G. When the punches have returned to their outermost position, then the sheets A and F can receive a traveling motion, and the above-described operation is repeated. Now in order to impart this intermittent traveling motion to the sheets A and F the following device is provided: A main shaft Q, extending transversely, is journaled in suitable hearings on the main frame J, and on one end of the said 'shaft is secured a pulley Q, connected by belt with other machinery for imparting a continuous rotary motion to the said shaft. On the shaft Q is secured a sprocket-wheel Q connected by a sprocket-chain Q with a sprocket-wheel Q, secured on one outer end of the shaft N, so that the rotary motion of the shaft Q is transmitted to the shaft N to actuate the punches, as previously explained; On one outer end of the shaft N is arranged a crank-disk Q carrying on its wrist-pin a pawl Q engaging a ratchet-wheel Q secured on one end of the shaft E of the drum E, so that an intermittent rotary motion is given to the drum E from the continuous rotation of the shaft N by the pawl-and-ratchet mechanism just described. A spring-pressed dog Q engages the ratchet-wheel Q to prevent accidental movement of the same. (See Fig. l.) The other end of the shaft E of the drum E carries a bevel gear-wheel R in mesh with a bevel gear-wheel B, secured on one end of a shaft R extending longitudinally and journaled in suitable hearings on the main frame J. Mounted to slide on the shaft R and to rotate therewith is a bevel gear-wheel R in mesh with a bevel gear-wheel R secured to the shaft Dof the pattern-sheet drum D, so that the intermittent rotary motion of the drum E is transmitted by the gearing described to the drumDto causethe drums to rotate intermittently in unison with each other and in the direction of the arrows indicated in Fig. 2. A shifting-lever R is connected with the bevel gear-wheel R to permit the operator to move the bevel gear-wheel R out of mesh with the bevel gear-wheel R whenever it is desired to do so for stopping the movement of the sheets F while adjusting the pattern-sheet A. When the machine is in operation and the drums D and E rotate intermittently, they impart a traveling motion to the sheets A and F, as described, so that the sheets unwind from the spools B and H, and when the last row of holes has been punched in the sheets F then it is desirable to rewind the pattern-sheet- A on the spool B and to rewind the punched sheets F on the spool H, so that the pattern-sheet is again in position for the next bunch of sheets F to be punched, while the spool H, with the punched sheets thereon, can be conveniently removed and replaced by another spool for the blank sheets. For the purpose mentioned the spool H is removably journaled on alined shafts H and H (see Fig. 6,) journaled in suitable hearings in the main frame A and provided with spring shifting-levers H H for moving the shafts H H outwardly to disengage the inner ends of the shafts from the spool H.

In order to rewind the sheets on the spools B and H, the following device is provided: On the main shaft Q, are secured pulleys S and S, connected by belts S S with pulleys 5 S mounted to rotate loosely on the shafts B and H of the spools B and H, respectively, and the said pulleys S and D are in the shape of clutch-pulleys, adapted to be engaged by clutches S S mounted to slide on and to turn with the shafts B and H. The

clutches S and S are normally out of engagement with the clutch-pulleys S and S so that the latter rotate loosely when the machine is in operation for punching the sheets F, as described; but when it is desired to rewind the sheets then the clutches S S are moved in engagement with the pulleys S S so that the shafts B and H, and consequently the spools B and H, are rotated in the inverse direction of the arrows shown in Fig. 2 to wind up the pattern-sheet A on the spool B and the punched sheets F on the spool H. During this operation the pawl Q is drawn out of engagement with the ratchet-wheel Q to allow rotation of the drums E and D in the reverse direction of the arrows shown in Fig. 2.

In order to hold the drumsDand E in proper alinementwith theirspools Band H,thedrums are pressed on at one end by springs E D and their shafts are pressed on at the other end by springs E D adjustable by screw-rods ED", screwingin the main frame J, as plainly indicated in Figs. 3 and 5, it being understood that the springs E D press against the outer pointed ends of the shafts E D of the said drums E and D. The spools B and H are similarly adjusted by the use of springs B H and adjusting-screws B and H, as indicated in Figs. 3 and 6.

In order to exhaust the air from the chambers P in the several tiers, the said chambers are connected with a vertical channel P (see Figs. 1, 3, and 4,) opening at its lower end into a main bellows T, carrying a plurality of exhaust-bellows T, actuated by suitable links 'I and levers T from a crank-arm T secured on the main shaft Q, so that while the machine is in operation the air is conveniently exhausted from the several chambers P to insure proper action of the pneumatics L, as previously explained.

The operation is as follows: When the several parts are in the position shown in Fig. 2 and the main shaft Q is rotated and an intermittent traveling motion is given to the sheets A and F, then whenever a transverse row of apertures in the sheet A registers with corresponding apertures in the tracker-board O, the corresponding pneumaticsL are caused to collapse to move the levers K and the punches I intoasetting position fortheactuating-shoulders N of the shaft N to impart a swinging motion to the said levers to cause the punches I to punch apertures in the sheets F corresponding to the apertures then in register with the openings in the tracker-board C. It is understood that during this operation the sheets A and F are at a standstill; but as soon as the punches I have returned to their uppermost inactive position then the sheets are again caused to travel as described to bring the next row of transverse apertures in the pattern-sheet A in register with the corresponding trackerboard openings, and the above-described operation is then repeated. Thus the sheets F are automatically punched to form sheets which are facsimiles of the pattern-sheet A, and when the sheets F are completely punched, as described, then the sheet A is rewound on the spool B and the punched sheets F are rewound on the spool H, after which the spool H is removed from the shafts H and H and a new spool having blank sheets thereon is replaced on the said shafts. The outer ends of the blank sheets F are now drawn over the die-block G to the drum E and fastened thereon and then the abovedscribed operation is repeatedthat is, the pattern-sheet A is drawn over the tracker-board O by the rotation of the drum D, while the sheets F are drawn over the dieblock G by the revolving of the drum E, as previously explained.

It is expressly understood that the pneumatics L simply move the punches into setting positionthat' is, for the shaft N to act on the levers K, which are setbut thepneumatics do not cause the punches I to punch the paper, and consequently little power is required for the pneumatics to perform their functionsthat is, to move the levers K and punches I into setting position.
